Answer:
2P4O10 + 2H2O → 2H3PO4
Balanced Equation → P4O10 + 6H2O → 4H3PO4
Tetraphosphorus Decaoxide + Water → Phosphoric Acid
Reaction Type → Synthesis
Answer:
Similarly, if magnet is held stationary and the coil is moved away and towards the magnet, the galvanometer shows deflection in similar manner. It is also seen that, the faster the change in the magnetic field, the greater will be the induced emf or voltage in the coil.

Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz
Answer:Use an excess of ethane
Explanation:
The halogenation of alkanes is a substitution reaction. All the hydrogen atoms in the alkanes could be potentially substituted. How ever the reaction can be controlled by using an excess of either the alkane or the halogen. If the aim (as it is in this question) is to minimize the yield of halogenated alkanes, an excess of the alkane (in this case, ethane) is used.
Answer:
5.46% is the percent by mass concentration of the solution.
Explanation:
Mass of LiBr= 8.2 g(Solute)
Mass of solution = 150 g (Solution)
Mass of solution = Mass of solute + Mass of solvent
Mass of solute < Mass of solvent (Always)
Mass of water = 150 g - 8.2 g = 141.8 g (solvent)
Mass percentage is given as:
5.46% is the percent by mass concentration of the solution.
